<DL>
<DD>Subdivides the quadratic curve specified by the coordinates
 stored in the <code>src</code> array at indices 
 <code>srcoff</code> through <code>srcoff</code>&nbsp;+&nbsp;5
 and stores the resulting two subdivided curves into the two
 result arrays at the corresponding indices.
 Either or both of the <code>left</code> and <code>right</code> 
 arrays can be <code>null</code> or a reference to the same array
 and offset as the <code>src</code> array.
 Note that the last point in the first subdivided curve is the
 same as the first point in the second subdivided curve.  Thus,
 it is possible to pass the same array for <code>left</code> and
 <code>right</code> and to use offsets such that 
 <code>rightoff</code> equals <code>leftoff</code> + 4 in order
 to avoid allocating extra storage for this common point.<DD><DL>
